Title: Change-speed gearing
IPC: F16D41/066
Filed: 1930-04-04
Abstract: 346,161. Driving machines. HERBERT, SIR A., Dunley Manor, near Whitchurch, Hampshire, and HARRISON, H. T., 44, Melville Road, Coventry. April 4, 1930, No. 10712. [Class 83 (iii).] In change-speed gearing for driving the spindle of a lathe or similar machine tool a belt-driven shaft 4 rotates a driving shaft 2 through gears 3, 5, preferably having a 1À1 ratio. The gears 5, 6 are secured to the shaft 2 and drive gears 7, 8, loose on a shaft 9 and capable of being selectively coupled therewith by friction clutches 10, 11 and a displaceable member 12. The shaft 9 carries easily removable pick-off gears 13, 14 meshing with similar gears 15, 18 secured to two lay shafts 17, 16 which carry gears 19, 20 engaging gears 21, 22 loose on a shaft 23 driving the lathe spindle 41 through a further train 42, 43. The gears 21, 22 may be coupled alternatively to the shaft 23 by friction clutches 24 and a slider 25, but preferably the slower gear 22 drives the shaft through a roller ratchet 26 which may be over-run when the clutch 24 is engaged. Alternatively, the clutches may be on the shafts 17, 16 and the gears 21, 22 secured to the shaft 23. A form of roller ratchet is described in which the gear 28, Fig. 2, is rotatably mounted on the shaft 29 by ball and roller bearings in its hub and is provided with an annular flange 33 having secured thereto blocks 34 located in the space between the flange and the driving member 32 keyed to the shaft. Rollers 38 loose in this space transmit the drive in one direction from cam blocks 36, engaging the flange, to the member 32, spring plungers 40 in the blocks 34 preventing chatter of the rollers during overrunning. The change-speed gears 7, 8, 21, 22 enable four different speeds to be readily obtained with any given pairs of pick-off gears 13 .. 18, and in an example, with the shaft 4 rotating at 600 r.p.m., pick-off gears may be selected to give a range of 8, 16, 200 and 400 r.p.m. of the spindle 41 or with other pick-off gears a range of 33, 65, 32 and 64 r.p.m. The shafts are mounted in ball bearings 44 and the loose gears are also preferably mounted on their shafts by antifriction bearings.

Title: Hydrocarbon conversion process
IPC: C10L1/06
Filed: 1960-03-30
Abstract: A number of refinery pool gasolines are obtained from a hydrocarbon feed stock by a process involving separating from the feed stock a fraction which is reformed to obtain a gasoline product, separating from the feed stock and/or the reformed product at least one aliphatic hydrocarbon in the C5-C7 range and subjecting this to pyrolysis at 1300-1750 DEG F. to obtain ethylene which is recovered as a product and C3 and/or C4 olefines which are subjected to a combining reaction to obtain a further gasoline product.  In a preferred embodiment a crude petroleum oil is distilled at 10 to obtain (1) C1-C3 gaseous hydrocarbons (2) a light gasoline fraction boiling in the range C4 to 160-200 DEG F. or to 210 DEG F. (3) a heavy gasoline reforming feed fraction boiling above (2) to an end point of 300-410 DEG F. (4) a virgin gas oil and (5) a residue.  The residue is subjected to thermal viscosity breaking at 11 and fractionated to at 12 obtain C3 and lighter hydrocarbons, a light gasoline fraction which is passed to distillation at 17 together with the light gasoline from 10, a heavy thermal gasoline passed to reforming at 15 or to blending at 25, a fuel oil and a thermal gas oil which is catalytically cracked at 13 together with the virgin gas oil from 10 and then distilled at 14 to separate C1-C3 hydrocarbons, gasoline which may be further distilled to obtain further feed for pyrolysis or reforming or passed to blending at 25 and fuel oil and heavy gas oil; a cycle oil may be recycled.  The heavy gasoline fractions are thermally or catalytically reformed conventionally at 15 and distilled at 16.  This distillation separates hydrogen for recycle and C1-C3 hydrocarbons, <PICT:0907087/IV (b)/1> a light gasoline, e.g. end point 160-200 DEG F. passed to distillation at 17 and a heavy gasoline passed to blending at 25 or 26.  At 17 the light gasolines are distilled to separate n-butane used as a gasoline constituent, isobutane and butylenes used as an alkylation feed to 23, isopentane used as a gasoline constituent and other aliphatic hydrocarbons which are pyrolysed at 18 in the presence of steam. From the quenched product ethane is recovered and further pyrolysed or dehydrogenated at 21.  Products recovered at 20 include a fuel gas, ethylene, butadiene, an aromatic gasoline which may be used as a gasoline blending constituent, an aromatic distillate and propane, propylene and butylenes which are subjected to alkylation with isobutane at 23. Propane and butane are separated from the alkylation product which is distilled and used as a gasoline constituent.  The combining reaction to which the pyrolysis product is subjected may alternatively comprise (a) thermal polymerisation; (b) catalytic polymerisation followed by hydrogenation; (c) alkylation of benzene; (d) hydration to isopropyl and tert butyl alcohols or diisopropyl ether; or (e) conversion of butylenes to tert butyl acetate.

Abstract: 1,119,403. Automatic exchange systems. GENERAL ELECTRIC CO. Ltd. 25 May, 1966 [17 March, 1965], No. 11319/65. Heading H4K. In a national system in which zone switching centres 1 . . . 6 are served by cable or radio links such as 7. . .15 connecting pairs of centres, each switching centre comprises a terminal switching unit 16 and a transit switching unit 17, the former connected by junctions 19 to exchanges of the zone and the latter to incoming and outgoing links, these units being generally similar and interconnected by links 18. On an incoming call over a junction 19a, a register in the terminal unit 16 takes the complete wanted number and a translator determines from the exchange code the required zone. If it is the same as that of the originating exchange, switching equipment is controlled to select an outgoing junction 19b. If not, a transit unit 17 is seized over a link 18a and the zone code is transferred to a register therein, and an associated translator determines first and second choice inter-centre routes, and indicates the route to be used. When a ready signal is received from the transit unit 20, for example, at the centre 2, the zone code is transferred thereto, and the call is further extended, either to the terminal unit at that switching centre, or over an outgoing junction to the transit unit of another switching centre. Inhibiting means is provided to ensure that an outgoing call is not directed over a route which includes the incoming junction. Moreover, at the originating switching centre the number of ready signals received from succeeding switching centres are counted, and if more than 3 junctions are connected in tandem, it is assumed that the connection is unacceptable, and NU tone is given to the caller. Features of the system are the subject of Specifications 1,119,401 and 1,119,402.
